GLOBE ATTACHMENT FOR ELECTRIC LAMPS.

SPECIFICATION forming part Of Letters Patent No. 571,802, dated November 24, 1896.

Application filed August 15, 1896. Serial No. 602,830. (No model.)

.To all whom t may concern.-

Be it known that I, EDWARD ScHRnN'rz, a citizen of the Ifnited States, residing at the city of St, Louis, State of Missouri, have invented a certain new and useful Improvement in Globe Attachments for Electric Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, wherein-- Figure l is a sectional view showing my iinproved attachment on a lamp-soeket- Fig. 2 isa top plan View of the globe-holder, showing my attachment in position. Fig. 3 is a plan View of my attaehmen t, showin g the same as being made of wire-gauze.

This invention relates to a new and useful improvement in globe attachments for electric lamps, the obj eet being to provide a perforated disk which closes the open end of the globe which surrounds the lamp, said disk being held in position by being' clamped between the flanged edge of the globe and the holder, the central part of the disk bein g supported by the lampsocket.

With this objectin view the invention ecnsists in an attachment consisting in a disk which is perforated centrally for the passage of the socket, the edges of said disk being clamped between the globe-holder and lian ged edge of the globe, whereby the open end of the globe is closed and insects, dirt, dust, the., are excluded from the globe.

In the drawings, A indicates an ordinary electric-lamp socket, which, as usually constructed, is formed with a beading a at its lower end.

B indicates the globe-holder, which may be of any ordinary or approved construction, said globe-holder having its outer edge turned downward to aiord a bearing for suitable globe-securing screws l).

C indicates the globe, of usual construction, the upper end being open to receive the lamp, the edges of said upper end being lian ged ontwardly, so that when the globe is placed in the holder the globe-securing screws may be screwed in under said flange to support the globe in position.

D indicates a disk formed of wire-gauze, as shown in Fig. 3, the edges of said disk being clamped between the flanged upper end of the globe and the globe-holder, whereby the disk is held in position.

When the disk is being applied, its centra-l opening has to be expanded, so that the beading a ou the lower end of the lamp-s0eket may pass therethrough, said opening, by reason of the yielding nature of the wire-gauze, immediately closing over the socket above the beading, making a tight joint. The beading now acts as a support for the center of the disk, preventingits sagging, as is obvious.

By the use of my invention insects which are attracted by the light, dust, dire., are eX- cluded from the globe, and therefore it is not necessary to clean the globe as frequently as has heretofore been done.

Having thus described iny invention, what I cla-iin, and desire te secure by Letters Patent of the United States, is

The combination with an electric-lamp socket, which is formed with abeading at its lower end, of a globe-holder secured to said socket aboye the beading, a wire-gauze disk 'formed with a central opening which is capable of being expanded to pass over said beading and close around the socket above the beading, whereby, the beading supports the center of the disk, and a globe which is supported by said globe-holder, said globe and globe-holder clamping the edges of the disk between them; substantially as described.

In testimony whereof I hereunto affix my signature, in presence of two witnesses, this 6th day of August, 1896.
